教材对“电感和电容对交变电流的影响”采用如图1、2所示的电路进行实验,实验的巧妙之处是对比了电感、电容对交流电、直流电的影响.但是,这两个实验实际上主要考虑了自感系数和电容对交流电的影响,只得出了容抗与电容有关,感抗与自感系数有关,而没有得出容抗、感抗与交流电频率的关系(教材直接给出结论,而不是通过实验得出结论).如果保持 Textbook on the “inductance and capacitance on the alternating current ” using the circuit shown in Figure 1 and 2 experiments, the experimental ingenuity is to compare the inductance, capacitance on the AC, DC, but these two In fact, the experiments mainly consider the influence of self-inductance and capacitance on the AC, and only get the capacitance-capacitance-related and inductance-induced self-inductance. There is no relation between capacitance and inductance and AC frequency The conclusion is given directly, not the conclusion of the experiment.) If maintained
